(\partial)/(\partial x)(z^2(sin(2xy)))

\frac{\partial}{\partial x} (z^{2} (sin (2 x y)))

z^{2} cos (2 x y) \cdot 2 y

Solution steps

\frac{\partial}{\partial x} (z^{2} (sin (2 x y)))

Treat

z, y

as constants

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= z^{2} \frac{\partial}{\partial x} (sin (2 x y))

Apply the chain rule:

cos (2 x y) \frac{\partial}{\partial x} (2 x y)

= cos (2 x y) \frac{\partial}{\partial x} (2 x y)

\frac{\partial}{\partial x} (2 x y) = 2 y

= z^{2} cos (2 x y) \cdot 2 y
